ENGINE-STARTING DEVICE.

Spccification of Letters Patent.

Application filedtictober 2, 1911. Serial No. 652,343.

To all whom it may cjbncem p Be it known that I, GEORGE J. BURKHARn'r, a citizen of' the United States, residing at Burlingame, in the county of San Mateoand State of California, have invented new and useful Improvements in Engine-Starting Devices, of which the following is a specification.

This invention relates to apparatus for starting internal Combustion engines The object of the invention is to devise andproyide an engine starting device of substantial construction, easy operat1on, of

few parts and such design that the engine may be started from any convenient position or location without cranking and thus avoiding' injury to operators. l

' The inventio-nconsists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in whichigure 1 is a partial sectional view showing'the device in position upon an engine Fig. 9 is a longitudinal section of same. Fig. "3 is a cross section on line X X.

The present form of my starter comprises a sleeve 2 slidahle upon a shaft 3 of an en- Agine. .The sleeve is provided with externalspiral threads 4 of desired pitch and one end of the sleeve is formed with clutch teeth 5, capable of engaging one or more projections 6 on the shaft 3.!

i The sleeve or clutch member Elis surerounded by a nut 7 slidable upon rigid guides 8 and also movable longitudinally with and relative the sleeve 2 which has a sto or flange 2 at one end. r l helongitudinal movement of the nu may be accomplished by operation of-a lever 9 connected by link 10 to the nut 7 and the initial movement of the nut first slides the sleeve 2 along the shaft until the clutch teeth encounter the projections 6 after v which further shifting of the nut imparts a rotary motion to the sleeve and consequently turnsthe shaft to start the engine. Should the engine speed up the projections 6, pushing against the inclined surface of the teeth,

force the. sleeve away into inoperative position. p

The extreme simplicity, inexpensive construction, strength of parts and positiveness of action, are important and valuable ob jects for which'this invention is devised.

If desired, a spring llfmay be connected to oneof the parts to maintain the sleeve 2 free of the projections 6 on the engine shaft.

The nut is adapted to shift along the sleeve until it engages the flange 2 when furtherv movement of the parts will be uniform.

- Having thus described my invention, What I claim and desire to secure by Letters Pat ent is- V An engine starting device comprising in combination a sleeve, an engine shaft upon which said sleeve isrotatably and slidably mounted, a bracket providing a bearing for enonen J. entertainer;
